/*
 Filter all fields and all rows in a recordset and returns the
 processed recordset. We scroll to the beginning of the new recordset
 after processing.

 We pass a recordset and function name to RSFilter($rs,'rowfunc');
 and the function will be called multiple times, once
 for each row in the recordset. The function will be passed
 an array containing one row repeatedly.

 Example:

 // ucwords() every element in the recordset
 function do_ucwords(&$arr,$rs)
 {
 foreach($arr as $k => $v) {
 $arr[$k] = ucwords($v);
 }
 }
 $rs = RSFilter($rs,'do_ucwords');
 */
function RSFilter($rs,$fn)
{
    if ($rs->databaseType != 'array') {
        if (!$rs->connection) return false;

        $rs = $rs->connection->_rs2rs($rs);
    }
    $rows = $rs->RecordCount();
    for ($i=0; $i < $rows; $i++) {
        if (is_array ($fn)) {
            $obj = $fn[0];
            $method = $fn[1];
            $obj->$method ($rs->_array[$i],$rs);
        } else {
            $fn($rs->_array[$i],$rs);
        }
         
    }
    if (!$rs->EOF) {
        $rs->_currentRow = 0;
        $rs->fields = $rs->_array[0];
    }

    return $rs;
